The **MHR14FFJ-R** is a specific electronic connector component, typically part of a series of High-Density D-Subminiature or Ribbon Cable connectors. While the prefix "MHR" can vary slightly by manufacturer (often associated with brands like **NorComp** or **Adam Tech**), it generally follows a standardized specification for industrial and computing applications. --- ### 1. Technical Specifications Below are the general characteristics typically associated with this part number: | Feature | Specification | | :--- | :--- | | **Component Type** | Connector / IDC Socket | | **Number of Positions** | 14 Pins | | **Mounting Type** | Through-Hole or Cable Mount (IDC) | | **Pitch** | Typically 2.54mm (0.1") or 1.27mm (0.05") | | **Gender** | Female (Socket) | | **Termination** | IDC (Insulation Displacement Connector) or Solder | | **RoHS Status** | Compliant (indicated by the "-R" suffix) | --- ### 2. Breakdown of the Part Number The alphanumeric string provides specific details about the part's construction: * **MHR**: Series prefix (Miniature High Reliability or Manufacturer Series). * **14**: Indicates the **14-pin count** (2 rows of 7 pins). * **FF**: Often denotes the gender and orientation (e.g., **F**emale **F**ront). * **J**: Specific housing or latching mechanism (e.g., Jumper style or Ejector latches). * **-R**: Indicates **RoHS Compliance** (Restriction of Hazardous Substances), meaning it is lead-free. --- ### 3. Key Components and Materials An electronic part like the MHR14FFJ-R consists of several critical elements: 1. **Housing:** Usually made of **PBT (Polybutylene Terephthalate)**, a thermoplastic that provides high insulation resistance and thermal stability. 2. **Contacts:** Typically made of **Phosphor Bronze** or **Brass**, plated with gold (in the contact area) and tin (in the termination area) for optimal conductivity and corrosion resistance. 3. **Strain Relief:** Often includes a plastic clip to prevent the cable from pulling away from the contacts. --- ### 4. Typical Applications * **Internal Computer Wiring:** Connecting motherboards to peripheral headers. * **Industrial Control Systems:** Routing signals between PCBs (Printed Circuit Boards). * **Telecommunications:** Used in data transmission equipment where high-density connections are required in small spaces. --- ### 5. Implementation Example (Schematic Context) In a PCB design environment (like Altium or KiCad), the footprint for this part would look like this: ```markdown Symbol: J1 (Connector) Pins: 1, 2, 3, ... 14 Footprint: HDR2X7 (2 rows by 7 pins) Pitch: 2.54mm ```
